“This week, Bloomberg BusinessWeek put the financial woes of the U.S. Postal Service on its cover with a story titled “The End of Mail.” The dire plight of the USPS isn’t exactly news — it’s been losing money since 2006, including nearly $20 billion since 2007. But the cliff the agency has been driving toward is fast approaching. The agency is now almost $15 billion in debt. Unless the government steps in, it will default on $5.5 billion of retiree health-care costs in September. By October it will reach its legal debt limit, and by the end of the year, the USPS will be out of cash — insolvent and unable to operate.” — Freakonomics Blog
